POSTIONING MEANS FOR ADJUSTABLE SUPPORTS.

Original application filed February 1, 1913, Serial No. 745,696. Dividedand 1913. Serial No. 772,598. l

To all 'whom t may concern Be it known that I, PETER A. SOLEM, acitivZen of the United States, residing at Cincinnati, in the County ofHamilton and State of Chio, have invented certain new and usefulimprovements in Positioning Means for Adjustable Supports, of which thefollow-l ing 1s a specification.

lvly invention relates to positioning means for adjustable supports, andis especially applicable to the support or housing which supports thehorizontally disposed cutterliead in wood planing machinery Aarranged tooperate on the upper side of the stock. I have shown and described myinvention in Yconnection with suoli housing, it being understood thatsaid horizontally disposed cutter-head may be the sole cutter-head inthe machine, or other cutter-heads operating for instance on the bottomo-r on one or more edges of the stock may be employed.

It is the object of my invention to provide new and improved means forpositioning a support of the character mentioned, Whereby said supportis clamped simultaneously and to equal degree Vat all clamping pointsfor insuring maintenance of adjusted positions of the support; and,further, to so construct and arrange the guiding means and so relate theclamping means theretor in novel manner as toy cause maintenance ofkadjusted relation of the parts; and the invention will be furtherreadily understood from the following description and claims, and fromthe drawings, in which latter:

Figure 1 is an end elevation of my improved device shown in connectionwith so much of a wood planing machine as is necessary to illustrate myinvention. Fig. 2 is a plan view of the same. Fig. 3 is a rear elevationof the same; and, Fig. 4 is a detail in section on the line 4 4 of Fig.3.

Patenten Nev. a, i913.

this application led June 9 n ent instance supports a rotarylcutter-head 13 and achip-brealrer 19 therefor, mounted 1n suitablemannenThe support is adjustable up and down on the guides 13.l This u support,shown as a cutter-head housing, has guideways therein cooperating with`said guides. The guideways are formed by rabbets at the respective endsof the housing,

these rabbets each having a bottolifwall 21 having a fiat bottomguide-face 22 and an end wall 23 having a flat end guide-face 24, theend guide-face 24 being perpendicular tO the flat bottom guide-face 22,plates n n 25 being secured to the end walls 23 by For effecting thesliding movement of the support, screw-rods 31 are threaded intothreaded lugs 32 on the support,the screwrods being j ournaled and heldlongitudinally stationary in bearings 33 in the main frame. Each of thescrew-rods has a bevelgear 34 secured thereto. 35 is a cross-shaft journaled in bearings 36 in the main frame and having bevel-gears 37 fastthereon, the bevel-gears 37 meshing with the gevel-gears 34. f Thecross-shaft has a turning means thereon, shown as a squared end 38adapted to be received in the squared socket of a suitable wrench, forturning Vsaid cross-shaft and thereby turning said screw-rods andadjusting said support upV and down.

After adjustment the support is clamped,y in place by Vclamping meanswhichk exert clamping stress in'fdirections at right angles to theopposed parallel clamping faces clamped, for clamping the Opposed wallsof they guideways and the guides at the respective ends of the supporttoward one another in directions perpendicular to their parallelclamping faces so as to Obtain a clamping agency exerting clamping`force over considerable area in such manner that the clamping actionwill avoid disturbance of adjusted `i'elation in the parts. I prefer toeti'ect the yclamping :by clamping the guides between the bottom walls21, which are rigid parts of the support, `and the plates 25 which havesuilicient resiliency toL Vwalls 21 of said guideways and pass throughslots 44 in the guides. A` set-nut 45 and a jam-nut 46 are screwed aboutthe outer threaded ends 4'( of each of said clampscrews.

ri'Curning means are provided for each oit the screws, shown in eachinstance in'the form of an arm 48 the hub 49 of which hasspline-connection with the clamp-screw for turning the clamp-screw uponswinging movement of thearm, but permitting relative axial movementbetween the clampscrew and the hub ot the arm. This splineconneotion isshown accomplished by a key 50 in the clamp-screw received in asplinegroove 51 in the hub.

The arms at the respective ends of the adjustable support are connectedby links 52 having articulations with said arms at 53 for causingsimultaneous movement of the clamp-screws at the respective ends of thesupport.

I further prefer to connect the clamping means atthe respective ends ofthe support, which I have shown accomplished by means of arms 54extending from the hubs'of the upper ones of the arms 4S, the armsi54being connected by a link 55 articulated therewith by articulations 56.The arms 54 preferably have hand-grips 57 thereon arranged to be graspedfor clamping or unclamping the adjusted support from positions at eitherside of the machine. The upper arms 48 and the arms 54 form bell-cranklevers.

By means of my improved device the ad justed support will be clamped inadjusted: position after adjustment without disar; rangingtheadjustment, and the adjusted support may be released 'to any desiredextent for providingV a looseor comparatively tight .sliding iit'betweensaid guide and guideways, as may be-desired for the purpose kofadjustment. It further provides means whereby the clamping strain actsupon faces of the guides and guideways which extend inplanes at rightangles to the axesiof the clamp-screws, whereby "endwise or otherdisplacement `of the 'adjusted support is prevented in the clampingoperation, which is especially desirable in that it preventsdisarrangement of the supported operative agency, exemplified as thecutterhead, with relation tothe stock-support or other operative portionof themachine. My improved device further provides means whereby theclamping action of each clampscrew may be adjusted, so that all of theclamping means may exert equal clamping action simultaneously, therebyaiding in avoiding disarrangement of the adjusted part.

Having thus fully described my invention, what I claim as new andLetters Patent, is:

1. In combination, a supporting structure having laterally outwardlyextending guides at the respective ends thereof extending up and down,each of said guides comprising opposed parallel guide-faces, and anadjustable support provided at each end thereof with aguideway havingopposed walls andan end wall, said guideways opening toward each otherwith said guides received between said opposed walls and said end wallsreceived outside said guides, said opposed walls provided with opposedparallel guide-faces parallel with and coperating with said first-namedopposed parallel guide-faces, and a plurality of interconnected clampingmeans between said opposed walls'respectively comprising connectingmembers between said opposed walls which are perpendicular to all saidopposed parallel guide-faces, and constructed and arranged forsimultaneously exerting clampingstress between and perpendicular to saidcooperating opposed parallel guide-faces, for the purpose described.

2. In combination, a supporting structure having laterally outwardlyextending guides at the respective ends thereof extending up and down,each of said guides comprising opposed parallel guide-faces, and anadjustable support provided at each end thereoil witha guiding rabbetcomprising a bottom wall and an end wall, said walls rigid with saidsupport, and a resilient guide-plate secured to each of said. end walls,said bot-tom wall and said resilient'guide-plate provided with opposedparallel guide-faces parallel with and coperating'with said i'irst-namedopposed parallelguide-faces, and a plurality of interconnected clampingmeans respectively comprising connecting members betweenisaid bottomwalls and resilient plates passing said llaterally,outwardly extendingguides and perpendicular to all said opposed parallelguide-faces,andconstructed and arranged for exerting clamping stress between andperpendicular to said -coperating opposed parallel guide-faces, for thepurpose described.
